The answer to 'why is my kitchen greasy' is that a buildup of grease and oil residue is a common problem in kitchens. This can be caused by cooking, splatter from food preparation, and lack of regular cleaning. Symptoms include a sticky, shiny film on surfaces, greasy smudges, and a lingering cooking odor.
To address a greasy kitchen, start by thoroughly cleaning all surfaces, including countertops, backsplashes, cabinets, and appliances. Use a degreasing cleaner and scrub well to remove the built-up grime. You may need to do this more frequently, such as once a week, to prevent excessive grease buildup. Ensure your kitchen has proper ventilation to reduce airborne grease and oil. If the problem persists or you're unable to fully clean the grease, it's best to call a professional cleaning service to deep clean your kitchen.
